of the tube a wire, a so-called mandrin, to give the necessary stiffness to the fiexible'soft rubber tube (drain) which wire is withdrawn as "3' soon as the probe has" reachedthe stomach.

In practice this relatively long wire-just on "account of itslength has not proved satisfactory, and has often causedcracks in the soft rubber tube f v In accordance with the present invention,

the .rubber tube is made oftwo or more sections to be connected as the tube is introduced,

- in combination with a mandrin having only the length of the first section.

On the accompanying drawing illustrating byway of example one embodiment of the invention: I A Figures 1 and 2 show on a reatly enlarged scale portions of the first an; second sections of the rubber tube in longitudinal section.

Figure 3 illustrates on the same scale the mandrin, that is, the wire for stiffening the first section of the tube as it is being introduced. v f Figure 4 shows the complete first tube section on a much smaller scale. Figure 5 shows themandrin by itself. Figure 6 shows the mandrin almost com pletely inserted into the first tube section. 0 Figure 7 the same, entirely inserted.

Figure 8' the second tube section, and finally Figure 9 the'two tube sections joined together.

The two tube sections designates respectively w1 and a2 are detachably connected with one another by means of a hose coupling b1 and b2.

The first tube section al-carries at its z lower free end the olive c-, which difi'ers 458,096, and in Hungary June 15, 1929.

from the naked olives hitherto used in that it is connected to a cap -(Z-. At both ends of a white (preferably silk) thread which is introduced through a bore e made on the side of the olive c, being I "then pulled out through the centre bore h of the olive and passed through the axial bore of the cap 0Z, knots g1 and 'g2- are provided, movably attaching the thredid .f to the olive c and to the cap The mandrin, that is, the wire m-, which, as mentioned above, is about as long as the first tube section a1-or only slight- 1y longer (for instance from 15 to 20 milli- 55 metres), is formed at its lower free end with a button m-, and is provided at its upper end with a handle. In the vicinity of the upper end of the mandrin m, but slightly (about 20 millimetres) beyond the first tube section,,is a collar -p, by means of which the movement of a member g, mounted displaceably on the mandrin m-, is limited in the downward direction. The lower part of member g is of the same dimensions as'the coupling member b2 of the second tube section -a2.,

Hitherto, the patient has had to swallow the probe without the help of the physician, who could not do more than give encourage- 9 ment. Now however the physician is able to intervene actively, independent of the the patient.

First of all, the physician will introduce 35 the mandrin minto the first tube section -a1 through the .coupling piece b1, pulling the thread '-fso far out by means of the knot g1, that the cap v d' touches the lower end of the olive 'c. Thereupon he screws the threading the introduction being attitude and feelings of of the member g into the female threading of the coupling piece b1, thereby stretching the flexible tube section a1 At the same time he fixes the thread f in the bore -h of the olive c by means of the button m,' of the wire, so that the cap d cannot fall off. 7

"The tube section -a1 prepared in this W3 manner is then pushed down by the physician into the stomach of the sitting patient I Without difiiculty through the open mouth,j

the throat and the gullet or esophagus. Then member g]- is unscrewed from the coupling piece '-b1 so that the mandrin m can be easily Withdrawn from the tube section al. The vbutton :4e-.'.of
